Three former ICAP Plc employees were charged by U.S. prosecutors and the interdealer broker was fined $88 million as the five-year-old probe into the rigging of benchmark interest rates ensnared another financial institution.

UBS AG will pay about $1.5 billion and two former traders face prison as the bank settled charges with U.S. and U.K. authorities for manipulating interest rates in a global conspiracy to boost profits and bonuses.
